"现代化服务器虚拟化解决方案比较与设计"

服务器虚拟化解决方案全文共22页，当前为第1页。 一、项目概况 随着业务的快速发展，IT已成为越来越重要的业务支撑保证。目前 IT 资源利用呈现一定分化的现象，并且在机房电力、空间、制冷上相对消耗较多，资源分配也不够灵活，服务器老化等，这些问题一直困扰着 IT 人员。项目概况： 1）优化 IT 架构 2）节约投资及运维成本 3）保障和提高生产力 4）高规格的数据安全措施 5）降低环境影响 二、方案设计 方案设计一（传统） 方案设计二（vSAN） 方案设计三（Nutanix） 三、方案对比 方案设计一（传统） 相对于超融合架构而言 优点: 1、易操作、易管理、稳定性较好 2、易于使用 SAN 进行备份 缺点： 1、对存储要求较高（性能、单点故障、扩展性） 2、计算与存储不能同时横向线性扩展 方案设计二（vSAN） 相对于 Nutanix 而言 优点 : 1、只需要一次性购买 VMware vSphere 和 vSAN 2、架构较简单,vSAN 是 VMware vSphere 内嵌的一个功能 缺点： In comparison to the hyper-converged architecture, the advantages include; ease of operation and management, as well as good stability. It is also easy to back up using SAN. The disadvantages include; high storage requirements (performance, single point of failure, scalability), and the inability to scale computing and storage simultaneously. The advantages of vSAN over Nutanix include; only needing to purchase VMware vSphere and vSAN once, as well as a simpler architecture in which vSAN is a feature embedded in VMware vSphere. Disadvantages include; high storage requirements (performance, single point of failure, scalability), and the inability to scale computing and storage simultaneously. Overall, the server virtualization solution aims to address the challenges of resource utilization and allocation, as well as to optimize IT infrastructure, reduce investment and operational costs, and enhance productivity and data security measures. By comparing traditional and modern virtualization solutions, businesses can make an informed decision based on their specific needs and requirements. The choice between traditional, vSAN, and Nutanix solutions will ultimately depend on factors such as ease of management, stability, storage requirements, and scalability.
